Tandem carbon-carbon bond insertion and intramolecular aldol reaction of benzyne with aroylacetones: Novel formation of 4,4′-disubstituted 1,1′-binaphthols
An efficient route to 4-aryl-2-naphthols from arynes and aroylacetones was developed by carbon-carbon bond insertion followed by an intramolecular aldol reaction and dehydration. Benzyne derived from 2-(trimethylsilyl)phenyl triflate reacted with benzoyla
